Previously, I have been a Marie-Curie postdoctoral fellow at the University of Durham between 2008 and 2010, and a postdoctoral scholar in Astronomy at Caltech between 2005 and 2008, working within Richard Ellis's group. I obtained my PhD degree from Université Paul Sabatier in Toulouse. I did my thesis work at the department of Astrophysics of the Observatoire Midi-Pyrénées, under the supervision of Roser Pelló and Jean-Paul Kneib. I have been working primarily in the Physics of galaxies group on galaxy formation and detection of the first generations of stars and galaxies.
